1. INTRODUCTION

Application

The VF05 two-wire guided microwave level transmitter is used to measure the distance, level, and volume of liquids, solids, and granules. The device can be used in

storage and reaction tanks, rigid pipelines of suitable diameter, and level reference vessels. The device is HART capable, it can be programmed using HyView software

or PACTWARE.

Operating Principle

The VF05 two-wire guided-microwave level transmitter measurement method is based on TDR (Time Domain Reflectometry) analysis of the electromagnetic pulse

traveling along the probe. The device sends nanosecond-wide, low-power pulses along an electrically conductive rod, cable, or coaxial supply line at a known rate of

light propagation speed. If the electromagnetic pulse propagating along the conductor reaches a medium boundary with a different (r) dielectric constant (the surface

of the measured medium or the phase boundary of two liquids), some of the energy is reflected from there. The larger and sharper the (r) dielectric constant change

at the boundary of the media, the better the efficiency of the reflection (e.g., 80% of the energy is reflected from a flat air-water boundary) is.

The pulse is detected and processed by the device as a voltage signal. Since the propagation speed is known, the distance of the reflecting surface can be determined

by measuring the travel time of the pulse. The travel time is the time between the start of the pulse and the arrival of the reflected pulse, and the distance traveled is

twice the distance to and from the target. The device calculates the distance from the measured time into an electric signal proportional to the distance, an output

current of 4…20 mA, and provides a HARToutput signal and displays it on the display. Other derived quantities (volume, weight, etc.) can also be obtained from the

distance data using the device software. The advantage of the described measurement technology compared to other level measurement methods is that the dust,

foam, steam, boiling, and surface turbulence have no disturbing effect.

3.2. ACCESSORIES

•Hyview software •2× M20x1.5 cable gland

•User and Programming manual •VGF-DISPLAY display unit (option)

3.3. CONDITIONS FOR SAFE USE

▪The metal housing of the device must be connected to the equipotential (EP) network.

▪The aluminum content of the cast aluminum housing exceeds the limit value, so the equipment must be protected against impact and friction.

3.4. MAINTENANCE AND REPAIR

VF05 does not require maintenance on a regular basis. In some very rare instances, however, the probe may need cleaning to remove deposited material.

This must be carried out gently, without damaging the probe. Repairs during or after the warranty period are carried out exclusively at the Manufacturer. The

equipment sent back for repair should be cleaned or disinfected by the User.

8 / 27

4. INSTALLING

4.1. HANDLING AND STORAGE

Lift the instrument using both hands, or if necessary, use a hoist. Do not lift the instrument

by the probe. It is a critically sensitive part.

Protect the instrument from mechanical impacts and falling. The electronics

is a sensitive and fragile unit.

Do not bend coaxial and rod probes.

The device must be supported in the marked places.

The cable probe must not be looped, broken, or frayed.

The minimum bending diameter is 0.4 m (16″).

All these may cause a measurement error.

Storage temperature:

4.2. MOUNTING ON CONTAINERS

4.2.1. General mounting instructions

The size and position of the connector on the top of the tank (and the distance from the wall), the internal anti-reflection fittings, the rough joints, the welds and the

shape and design of the top and bottom of the tank are very important for the correct operation of the device. Any factor that affects the formation of the electromagnetic

field of the probe also significantly impairs the measurement accuracy. The coaxial probe is an exception because it has no external electromagnetic field.

Threaded process connection

Lifter height

Lifter intrusion into the tank

The easiest way to mount onto the tank is with a

device screwed into a 1 "BSP, 1" NPT, 1½ "BSP

or 1½" NPT threaded hole.

Do not use a lifter longer than the probe diameter

for individual probes and dusty applications.

h ≤ Ød, where

h = lifter height

Ød = lifter diameter

Consult HYCONTROL if the above condition cannot

be met!

The lifter must not extend into the tank,

as the protruding part interferes with the

measurement!

9 / 27

Mounting two devices

Effects of material influx

Using a protective tube

If two devices have to be mounted on one

tank, they must be spaced at least 2 m

(6.5 ft) apart to eliminate interference and

measurement inaccuracies resulting from

the interaction of the two electromagnetic

fields.

Devices equipped with coaxial probes are

not subject to the above warning because

there is no electromagnetic field outside the

probe's outer sheath.

Do not place the lifter near the material inlet

pipe connector.

Material flowing onto the sensor probe causes

incorrect level indication. If there is not enough

space, it is recommended to install a baffle plate.

The floating lid is a common solution for petrochemicals. In

such cases, the use of a damping tube is recommended.

Straightness and contact of measuring probes

with other fittings and distance from the bottom of the tank.

Using a stirrer

After installation, the cable probes and the associated tensile weight

must be straight, tensioned, and away from other fittings (e.g.,

mixer). They must not come into contact with the tank wall, bottom,

or other objects.

The installation space requirements of the different measuring

probes must be taken into account according to the data of the

measuring probes (see Technical Data).

There is no radiation cone along the probe.

When measuring liquids, the use of a reference chamber or damping tube is

recommended, since it provides mechanical and electromagnetic protection for accurate

measurement.

Protect the device from direct sunlight!

Attaching the probe to the bottom of the tank.

Flexible cable probes can be anchored to the bottom of the tank with a fastener or loop.

Installing and shortening the cable probes

If necessary, the probe can be shortened, but only for liquid applications.

Steps:

1. Loosen the grub screws (hexagon) with an Allen key. (ISO 2936)!

2. Pull the cable out of the tension weight and cut to the desired size!

3. Insert the cable back into the weight as shown and tighten the screws!

4. Modify the configuration parameters to the new length, the reference point being the

upper edge of the weight!

4.2.2. Installing the Device for Measuring Solids

False measured value

Coning and strong tensile force on the probe

The probe may not touch the lifter pipe

Strong tensile force. The rope must not be

anchored when measuring solids.

The device is mounted at a distance of half the

radius of the tank from the top of the tank with a

minimum lift nozzle height.

It prevents excessive mechanical stress when

emptying the tank.

The tensile force of the probe rope depends on the height and shape of the

tank, the fragmentation of the material, the density, and the speed of

discharge.

The following table gives the tensile load values for the different materials

(approximate data in tons).

The measured process material can accumulate on the probe and lifter, which weakens the energy of the measuring pulse.

Avoid creating cavities that increase deposition.

Observe the load capacity of the tank top, which must ensure the maximum tensile force of the probe.

4.3. WIRING

Wiring in non-explosive environments

1. Take the device’s lid off.

2. Put the cable through the cable gland (½" NPT) to the terminal block.

3. Remove the outer insulation for ~80 mm (~3.15″) from the cable so the wires can be accessed, then strip the

wires for 4 mm. Strip the shielding from the signal cable.

4. Connect the cable to terminal 2 and 3 (polarity is irrelevant).

5. Retract the cable so the cable’s outer insulation runs through the cable gland for about 10 mm (0.4″). Then

tighten the cable gland’s nuts with two wrenches.

6. Organize the wires in the compartment.

7. Put the lid back on.

Do not perform insulation tests with a test voltage of 500 V AC on the device due to the internal electronic

surge protection!

Connecting (grounding) to equipotential network (EPH)

Electrostatic discharge (E.S.D.)

Threaded earth connection (EP) on the side of the housing,

maximum wire cross section: 4 mm² (AWG12). The housing of

the device must be earthed to a ground with a resistance of

R1 Ω.

The shield of the test lead must be earthed at the instrument

panel. Do not run the test lead near high-current cables, as

shielding does not provide protection against switching

harmonics.

The device is protected against 4 kV ESD.

Warning: The electrostatic discharge protection of the

measuring system cannot be solved by the internal ESD

protection.

In all cases, it is the user's responsibility to ensure that the

tank, measured material, and probe are grounded.

Risk of injury!

The probe may accumulate an electrostatic charge during

regular operation, so discharge it to the ground by touching

it (tank side) when installing!

Ground the inlet and the measured medium!

RHART resistance for HART®communication

250 Ω (recommended)

Line A: minimum voltage on the device’s input terminals

Line B: minimum supply voltage (voltage drop on the device and the 250 Ω loop

resistance)

An example for calculating the supply voltage:

The minimum supply voltage at Imin = 4 mA current:

Usupply min.= Uin min.+ (Imin * loop resistance) = 12 V + (4 mA * 0.25 kΩ) = 13 V

The minimum supply voltage at Imax = 22 mA current:

Usupply min.= Uin min.+ (Imin * loop resistance) = 11.5 V + (22 mA * 0.25 kΩ) = 17 V

Therefore, if the loop resistance is 250 Ω, 17 V is just enough for the entire 4…20 mA

measuring range.

12 / 27

4.3.1. BUS (HART®) communication

The output of the device can be used in two ways: 1. Current loop output and HART®2. Passive, HART®protocol

The HyView program supports the use of both modes.

According to the Rosemount Standard, HART®communication can be used as a point-to-point connection between VF05 as a “slave” and a HART®“master”.

There are two modes of communication:

•If the device (HART®short address 0) is set to current loop transmission (4…20 mA), only one device can be in the HART®communication loop

•For multidrop operation (4mA), several devices (max. 15) can be connected to one HART®communication loop. In this case, a short address other than 0

must be set for the device.

4.4. SWITCHING ON AND COMMISSIONING

The VF05 two-wire device is supplied by HYCONTROL with the technical specifications requested by the customer, so it is ready for operation immediately after

installation and wiring up.

Measuring starts less than 20 seconds after switching on. Attention! The initial current consumption of the device is 3.5 mA right after switching on! If there is

a change in the installation data due to shortening a cable probe, the set parameters must be changed according to the application before starting the measurement.

4.5. AVAILABLE USER INTERFACES

The instrument can be programmed by using the following devices / accessories:

VGF-DISPLAY display unit

Ordered separately. See ”5.2. Programming with the VGF-DISPLAY display unit.”

Hyview software (PC needed)

Available as download

HART®Microlink USB modem

5.1.2.2 Setting Up and Filling the OC (Output Conversion) Table

This feature is required to create a level / volume conversion table of up to twenty points. Each new value entered must be greater than the previous one.

The length and volume units can be changed later without changing the data in the table (length unit, volume unit).

The two units on the right and left of the table are given by the length unit and volume unit settings, i.e., these two units must be used to complete the table (length

unit and volume unit).

Important: Volume can only be measured if a conversion table is created!

To fill or adjust the device level / volume table, go to the “Device Setup”> “OC-table” tab in HyView.

Here you can fill or modify the table.

The difference is that if the “Measurement mode PV source” parameter is set to “Volume” or “Ullage Volume”, the OC table is active.

When the appropriate changes have been made to the table or it has been filled in correctly, click the “Send” button under the “Get” button on the right on this page

(“OC-table” tab) to download the table.

the popup window.

5.1.2.4 Device “Echo Diagram” (Oscilloscope Function)

Open the “Echo Diagram” window to display the device echo diagram.

The “Device Echo map” window will appear. The diagram shows the reflection curve measured by the device.

Press the “Refresh” button in the bottom row of the window (or press the F4 button while in the window) to refresh the chart or read the data. After a successful

reading, a curve corresponding to the image below will appear on the graph (see Figure 1).

If there was an evaluable level signal, it will also appear on the graph (“Selected peak” bubble window) along with other additional information. In addition, you can

use this window to set any “Threshold” level.

5.1.2.5 Level Threshold

The level threshold of the device can be changed in the echo diagram window, i.e., the value of “Threshold.”

This may be necessary if the device does not find the level signal (e.g., the set level threshold is too high or too low and the gain is already at the highest level).

To change the “Threshold” value, access the “Threshold settings”> “Threshold edit enable” function from the pop-up menu triggered by a right-click. The corner

points of the threshold curve on the echo diagram can then be adjusted with the mouse. Pressing the “Apply Threshold” button on the left help panel will apply the

set threshold value. To refresh the chart, press the “Refresh” button (or press the F4 button in the window).

Attention! The “Cursor On” function does not give an exact

value, it only recalculates the value of the given point based on

the graphical representation.

Press the “X” close button to exit the device settings window.

Creating a volume table –(HyView OC-table (OCT))

A conversion table has to be created using HyView to measure volume.

The volume values in the table are assigned to the measured levels. For asymmetrical and irregularly shaped containers, the accuracy of the volume measurement

depends on the number of pairs of values associated. The maximum number of pairs is 20. The volume is determined by linear interpolation between two value

pairs. The conversion table is usually used for volume measurement, but can also be used for weight or flow measurement.

The following example shows five-point programming.

Here's how to create a user-defined "level-to-volume" conversion table (using HyView).

A maximum of 20 points can be entered. Each level and volume point must be entered.

Each subsequent point must be larger than the previous one.

New lines can be created by pressing Ctrl + Insert, or by selecting “Add new item” in the right mouse button popup menu.

Lines can be deleted by pressing Ctrl + D.

Note: The level can be measured effectively between 0.20 m (0.66 ft) and 5.60 m (18.5 ft).

When the level of the measured material falls below the end of the measuring probe, the device

will still indicate 0.20 m, because the level meter can only display between 0.20 m (0.66 ft) and

5.60 m (18.5 ft) according to the probe length (which is now 5.8 m [19 ft]).

The size of the dead zone depends on the equipment and the type of probe.

5.2. PROGRAMMING WITH THE VGF-DISPLAY: DISPLAY UNIT

The most important parameters of VF05 can also be set with the VGF-DISPLAY: display unit.

By default, the display shows the primary measurement result (from which the output current is calculated).

In addition to the measured value displayed in large numbers, a bar graph representing the value of the output current is also shown on the right.

Programming is done using a text menu. You can use the

/ / / buttons to navigate the menu.

5.2.1. VGF-DISPLAY: Display Unit

Display

64 × 128 dot matrix LCD, signs, units and bar graph

Ambient temperature

Housing material

PBT fiberglass, plastic (DuPont)

The plug-in module containing the VGF-DISPLAY: LCD display (universal - can also be used in other HYCONTROL

devices, provided the device software supports VGF-DISPLAY:).

Warning!

The VGF-DISPLAY: uses an LCD, do not expose the VGF-DISPLAY: to prolonged exposure to strong heat or sunlight as

the display may be damaged.

If the VF05 cannot be protected against solar radiation not possible or it is used outside the operating temperature

range of the VGF-DISPLAY:, do not leave the VGF-DISPLAY: in the VF05!

5.2.2. The Behavior of the VF05 while Programmed Manually

By default, VF05 displays the main measurement data on the VGF-DISPLAY: display (hereafter referred to as display).

Enter the programming menu by pressing the

button. Use the / buttons to navigate through the menu items.

Enter the selected menu item with the

button. Return to the previous menu level with the key.

The buttons only work if the VGF-DISPLAY: is present!

The device continues measuring while the menu is accessed. Changes made in the menu take effect when you exit the menu.

If you do not exit the VF05 menu, the device will automatically return to the measurement display state after 30 minutes. In this case, any changes made in the menu

will be ignored.

If the VGF-DISPLAY: is pulled out of the VF05, the VF05 will automatically exit the menu and ignore any changes made in the menu.

Since programming with VGF-DISPLAY (manual programming) and remote programming on HART (REMOTE MODE) create a conflict, only one mode can be used

at a time.

Manual programming has priority overt HART!

During manual programming, the device sends a “device is busy” signal to the HART master (HART Response code: 32 – Device is busy).

In remote programming mode, REM is displayed on the top right of the display. In this case, manual programming of the device is disabled, the menu cannot be

accessed.

If no VGF-DISPLAY: is connected, the LEDs will be visible, the flashes of the COM LED will indicate HART communication, and the VALID LED will indicate if the

data measured by the device is valid.

5.2.3. Manual Programming

Press the
